6 FAQs about [Energy storage electrical equipment Disconnection electrical equipment]

What is an ESS equipment disconnect?

An ESS equipment disconnect should be able to de-energize the equipment from all power sources and monitor that the system stays de-energized as long as needed. Source disconnects isolate power production equipment from the remainder of the premise wiring.

What are electrical energy storage systems (EESS)?

Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years. EESS are starting to be used for other purposes.

Where are equipment disconnects located?

Equipment disconnects are usually located on or adjacent to the equipment they disconnect and need to be lockable in the open position in accordance with 2017 NEC 705.22 and 2020 NEC 706.15.

What is the IET Code of practice for energy storage systems?

traction, e.g. in an electric vehicle. For further reading, and a more in-depth insight into the topics covered here, the IET’s Code of Practice for Energy Storage Systems provides a reference to practitioners on the safe, effective and competent application of electrical energy storage systems.

What is a load disconnecting system?

Disconnection means is an important consideration with these systems. This information is found at 706.8 (A). It is crucial that the load disconnecting means serving multiple sources of power disconnects all energy sources when in the off position. This helps to ensure worker safety, as well as the safety of the equipment and the structure.

Do I need a source and equipment disconnect?

Depending on the ESS design and components, a combination of source and equipment disconnects might be needed to isolate the ESS from other systems, the premise wiring, and the utility grid. Disconnect devices may satisfy source and equipment requirements within a single enclosure or switch.
